deff fn [24]

Answer:

Step-by-step explanation: How do you find the 3rd angle of a triangle?

Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.

The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.

(2x105)/(3x103) + 3x103 * 5x102
AleksAgata [21]

Answer:

1500066.66

Step-by-step explanation:

Given: (2\times10^{5} )/(3\times 10^{3} ) + 3\times10^{3} \times 5\times10^{2}

Now, simplifying it.

Using PEDMAS in solving the expression

First opening the parenthesis

= 2\times10^{5} /3\times 10^{3}  + 3\times10^{3} \times 5\times10^{2}

Next dividing the number

as per law of indices, x^{m} \div x^{n} = x^{m-n}

= 2\times10^{5-3} /3 + 3\times10^{3} \times 5\times10^{2}

= 2\times10^{2} /3 + 3\times10^{3} \times 5\times10^{2}

= \frac{2\times10^{2} }{3}  + 3\times10^{3}  \times 5\times10^{2}

Next multiplying the number as per PEDMAS

as per law of indices, x^{m} \times x^{n} = x^{m+n}

= \frac{2\times10^{2} }{3}  + 15\times10^{3+2}

= \frac{2\times10^{2} }{3}  + 15\times10^{5}

= \frac{2\times 100}{3}  + 15\times10^{5}

Next dividing the number as per PEDMAS

= 2\times 33.33  + 15\times10^{5}

Next multiplying the number as per PEDMAS

= 66.66+1500000

Now adding the number

= 1500066.66
